If the person being called does not have caller identification, she or he will have no way of knowing that the number is blocked.
If the person you blocked calls your number, they'll go to voicemail and can leave a message, but you won't get a missed call or voicemail notification.
There is no surefire way to retrieve call history from a blocked number, as the very nature of blocking a number means that the caller's information is hidden from view.
It's a normal call when you call a person and hear the usual number of rings before getting voicemail. But if the person has blocked you, here's the big indicator. You only hear a single ring before being diverted to voicemail.
So the person who was blocked won't know they're blocked when they try to call you. On their end, they'll hear the phone ring a few times. Then, their call will go straight to voicemail. Here is the one big catch with blocking someone on iPhone.
Unfortunately, since you have been blocked, there is no way to get your texts delivered. However, there are some sidesteps that you can try to text someone who blocked you on Android. Another way to text someone who blocked you on Android is to use an anonymous texting service. As you can tell by the name.
If someone has blocked you, you cannot text them. However, there are various ways to message someone who has blocked you. Although these methods do not send text messages, they will undoubtedly convey your message.
Messages that are sent or received won't be delivered. Also, the contact won't get a notification that the call or message was blocked.
Some spammers may spoof the Caller ID. It is possible that they are not calling from a real number. If they are disguising their identity by falsifying the caller ID information, this is called caller ID spoofing.
Dial *67. This code will block your number so that your call shows up as an "Unknown" or "Private" number. Enter the code before the number that you're dialing, like so: *67-408-221-XXXX.
If you still want to check if you have been blocked or not, you can try to call with some other number. If the phone rings more than once, you have been blocked.
When a number or contact is blocked on your Apple® iPhone®, calls are sent to Voicemail, but no voicemail notifications are received.
Android phones move all blocked messages into a folder on the phone called “Spam and Blocked.” That means that the phone is still collecting messages from the blocked people; they just aren't notifying you. This can be a lifesaver in needing those blocked messages for various reasons after the fact.
If an Android user has blocked you, Lavelle says, “your text messages will go through as usual; they just won't be delivered to the Android user.” It's the same as an iPhone, but without the “delivered” notification (or lack thereof) to clue you in.
If you send a message as a regular SMS in the green text bubble and you do not get a “Delivered” notification but instead get a notification similar to “Message not Delivered” or no message at all, that means you were probably blocked.
To know if someone blocked you on iPhone, try sending both an iMessage and SMS message. You can also check if you're blocked on social media apps, or try a different number or device. It's hard to know for sure if you're blocked, as it could also be Do Not Disturb or Airplane Mode.
If you've been blocked, the recipient will not receive a notification and won't be able to respond. If you don't receive a returned call or text message within a few days, there's a good chance you may be blocked.
That's the way Apple handles blocking–all iOS blocks calls and automatically routes them to your voicemail. This means that blocked number may still leave you a voicemail but you will not know they called or that there is a voice message.
Try sending a text message
However, if a person has blocked you, you won't see either notification. Instead, there will just be a blank space beneath your text. It's worth noting that being blocked is not the only reason why you might not see a notification.
If you have confirmation that someone has blocked your contact on their phone, there's no way to unblock yourself remotely using any of your devices. To unblock your number, you need to either have physical access to the person's phone or talk the situation through with them and have them reverse the action.
When you block a number on your Android phone, your phone won't ring when the person calls you, but the caller can still leave voicemails. The only way to prevent callers from leaving voicemails is to use an app that labels blocked numbers as spam.
If you only hear one ring before the voicemail picks up, there are three possible reasons: their phone is off, they've set their phone to auto-divert to voicemail (i.e., they've enabled Do Not Disturb mode), or you've been blocked.
